Copy Handler

Yesterday, the first beta version of Copy Handler was released. It features separation of data reader and writer to separate threads (it should improve copy performance) along with various bugfixes and optimizations.

Changes were bigger than expected, so the new version is released as beta.

Lately I have received several reports about Copy Handler being reported by Malwarebytes scanner as PUP.Optional.Unizeto.

The short version is that Copy Handler is safe to use and Malwarebytes report seems to be inaccurate. I have reported the problem to Malwarebytes - hopefully they will be able to fix it.

The problem is detected only in portable version of CH - installer version seems to be unaffected (both as installer exe and as already installed version). But as soon as you zip the installed version, Malwarebytes detects the PUP.Optional.Unizeto and tries to quarantine file.

PUP.Optional.Unizeto seems to be related to unwanted software (toolbars and other) that is bundled with some legitimate software. Copy Handler was never bundled with any other software, nor its installer included any other software. The only link I can see is that Copy Handler uses the code-signing certificate issued by Unizeto/Certum which is completely legitimate company that issues certificates.

This new version improves integration and cooperation with third-party software (including Explorer), includes Turkish translation from Onur, fixes handling of retry in case of read/write errors and fixes several other bugs.
